I'm home learning a course/certificate for pen-testing and security analysis. I came into a part in the process of pen-testing Perimeter Devices, specifically at testing the Router.
At this point I'm advised to do a Testing for Package Leakage at the Router. A little explanation in that part stats that some router may disclose its identity while connecting on certain ports.
'Cisco' in the payload with a
'RST' response after connecting on port
Unfortunately, there is no more information about this part even after I did some search. So my questions are:
What is Package Leakage?
What exactly this step and how to try it for any Router?
How this is differs from
What tools (if any) to use in this test?
